I don’t know how to generate the tab-delimited file you mention, but SDCC includes an 8051 simulator that – I imagine – would be able to run a FreeRTOS program if you could get it compiled.  The simulator is called uCSim.  I don’t know the exact relationship between the SDCC project and the simulator developers, but you can find more information at either: [http://sdcc.sourceforge.net/](http://sdcc.sourceforge.net/) [http://mazsola.iit.uni-miskolc.hu/~drdani/embedded/s51/](http://mazsola.iit.uni-miskolc.hu/~drdani/embedded/s51/)
